如何正确使用两次moment.updateLocale？

Question

I try to moment.updateLocale twice in different functions.

I expect the code to print

Today1 12:00 am
Today2 12:00 am

But right now it prints

Today at 12:00 AM
Today1 12:00 am

jsbin

function showTime1(dateTime) {
  moment.updateLocale('en', {
    calendar : {
      sameDay : '[Today1] h:mm a'
    }
  });

  return dateTime.calendar();
}

function showTime2(dateTime) {
  moment.updateLocale('en', {
    calendar : {
      sameDay : '[Today2] h:mm a'
    }
  });

  return dateTime.calendar();
}



console.log(showTime1(moment().startOf('day')));
console.log(showTime2(moment().startOf('day')));

Answer 1

I found that I should use calendar directly in this case. The API document is here .

jsbin

function showTime1(dateTime) {
  return dateTime.calendar(null, {
    sameDay: '[Today1] h:mm a'
  });
}

function showTime2(dateTime) {
  return dateTime.calendar(null, {
    sameDay: '[Today2] h:mm a'
  });
}



console.log(showTime1(moment().startOf('day')));
console.log(showTime2(moment().startOf('day')));
